Specification of Letters Patent.

Patented Nov. 1 1, 1913.

Application filed April 4, 1913. Serial No. 758,924.

To (ZZZ whom it may concern:

Be it known that I, WILLIAM J. Bnn'rnn, a citizen of the United States,residing at Louisville, in the county of Jeflerson and State ofKentucky, have invented certain new and useful Improvements in Rail-Chairs, of which the following is a specification.

This invention relates in rail chairs.

The primary object of the invention is to provide a chair to receive themeeting ends of railroad rails with means for effectually Wedging eachof the rails in the chair and so arrange the Wedging means that themembers which constitute the same prevent the displacement of eachother.

A further object of the invention is to provide a chair with raillocking means which may be conveniently assembled on the chair, thelocking means constituting I are held against displacement by meansother than ing contact with the rails or the chair.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which Figure l is aside elevation; Fig. 2 is a perspective view of the chair; Fig. 3 is asection on the line 38 of Fig. 1; Fig. 4 is a perspective view of one ofthe wedge members; and Fig. 5 is a section on the line 5-5 of Fig. 1.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying draw ingby the same reference characters.

In the drawings, 10 designates the chair which consists of the base 11and the 1ongitudinally extending side or web portions 12 and 13 whichembrace the web of the rail. The side portion 13 is formed at its endswith the laterally extending portions let which are formed integral withthe base 11, these lateral extensions being each-provided with athreaded aperture.

The inner faces of the webs 12 and 13 conform generally to the shape ofthe rail. The inner face of the web 13 is provided with a groove 15which is curved transversely and which is deeper at the ends of the webthan at its center, the groove gradually decreasing in depth as it nearsthe center of the web.

The chair is secured to the cross ties by to an improvement other andwith the their wedgwedge members are bolts which engage the edgeportions of the base 11. The meeting ends of the rails are insertedbetween the webs 12 and 13, and with their ends thus assembled 'a wedgemember 16, such as is shown in Fig. 5, is inserted in each end of thechair; The wedge members 16 are provided with rounded surfaces 17,which, when a member is inserted, enters the. groove 15 of the web.

The wedges are of a length approximately equal to the length of thechair, and when a Wedge member 16 is inserted in each end of the chairthe tapered portions 18 of the members overlap. Thus, when the wedgesare driven firmly into place, their rounded portions 17 enter the groovelo of the web and exert pressure against the rail at the ends of thechair. The overlapping portions of the wedge members create a greaterbinding action as they contact with each web and the rail shallowportion of the groove 15.

The wedge members 16 are each provided 2 with a lug 19 formed withanaperture 19 disposed to aline with the aperture of the adjacent lateralextension 14 when the driven into place. A threaded bolt 20 is aperturesin the lug and extension, the head 21 of the bolt contacting with thelug, there being a pin 22 inserted through the bolt adjacent theextension 14 whereby it is supported against displacement. noted by thisconstruction members after having been will be effectually lockedagainst movement relative to the chair, regardless of the wedgingconnection of the members with the chair and rail.

that the wedge driven into place at the i inserted through the It :willbe The many advantages of a construction of this character will beclearly apparent, as it will be noted that the device provides a simpleand effective locking mechanism for the meeting ends of rails in whichthe locking members are maintained against displacement by their bindingaction with the rails, there being an auxiliary locking mechanismprovided for holding said members in contact with the rails.

It will also be noted that the entire structure' is such as may beeasily and economically manufactured, and that the various parts may bereadily assembled.

What I claim is:

1. A rail joint comprising a chair which includes a base andlongitudinally extending webs, the inner face of one of thewebs belngformed'with a groove which is ta- H 7 ing groove which is curved '7 15pered adjacent the terminals of the web,

and wedges disposed to enter the groove from opposite ends, the wedgesoverlapping and contacting with the meeting ends of the rails which arereceived" between the webs,

2; A'railjoint comprising a chair whi'ch includes ab-ase andlongitudinally extending webs between which the meeting ends of therailsarereceived, one of the webs being. formed with a longitudinally extend-I w transversely aoent I the deeper adjacent said'ends than at itscentral portion, wedge members flattened adj acent their smallerterminals and rounded Copies of this patent may 'be obtains adjacenttheir l-argerterminals, said wedge the groove of theweb members enteringfrom opposlte ends, and means for locklng said wedge members to thechair.

3. A rail joint comprising a chair which ends of the web andwhich isadjacent their larger terminals, the wedge members entering the groovefrom opposite ends, said wedge members being provided with extensions,and bolts passing through said extensions and means formed integralw-i'th'the chair, whereby the wedge members are supported againstmovement with respect to the chair.

In testimony whereof I aflix my signature in presence of two witnesses.
